Enum Error 

#[non_exhaustive]
pub enum Error {
    Config(String),
    Exporter {
        signal: &'static str,
        source: Box<dyn Error + Send + Sync>,
    },
    SubscriberAlreadySet,
    Prometheus(Error),
}

Available on crate feature observability only.

Observability setup errors.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Config(String)

The configuration is invalid.

Exporter

An exporter could not be built.

Fields

signal: &'static str

traces, logs or metrics.

source: Box<dyn Error + Send + Sync>

The underlying error.

SubscriberAlreadySet

A global tracing subscriber was already installed.

Prometheus(Error)

Available on crate feature prometheus only.

The Prometheus exporter could not be built.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Error

Converts to this type from the input type.
